solve a riddle
Suppose the price of a mysterious chair is X yuan. If we buy 14 such chairs and 14 more expensive tables with 7 yuan money, the total cost will be 1 162 yuan. So, what's the price of each chair?
solve an equation
We can solve this problem by solving equations. According to the meaning of the question, we can list the equation:14x+14 (x+7) =1162. Then, we simplify the equation and get 28X+98 = 1 162. Then, we move 98 to the other side of the equation and get 28X = 1 162-98. Finally, we divide by 28 to find the value of x, and get X = 38.
calculative price
According to the value of X we worked out, the price of each chair is 38 yuan. The price of the table is the price of the chair plus 7 yuan, which is 45 yuan. So, the answer is: table 45 yuan, chair 38 yuan!
